实例扩容

功能介绍

实例规格变更。当前通过调用API，只支持按需实例进行实例扩容。

调用方法

请参见如何调用API。

URI

POST /v2/{engine}/{project_id}/instances/{instance_id}/extend

表1 路径参数

参数

是否必选

参数类型

描述

engine

是

String

消息引擎。

project_id

是

String

项目ID，获取方式请参见获取项目ID。

instance_id

是

String

实例ID。

请求参数

表2 请求Body参数

参数

是否必选

参数类型

描述

oper_type

是

String

变更类型。

取值范围：

  • storage：存储空间扩容，代理数量不变。

  • horizontal：代理数量扩容，每个broker的存储空间不变。

  • vertical：垂直扩容，broker的底层虚机规格变更，代理数量和存储空间不变。

new_storage_space

否

Integer

扩容后的存储空间。

当oper_type类型是storage或horizontal时，该参数有效且必填。

实例存储空间 = 代理数量 * 每个broker的存储空间。

当oper_type类型是storage时，代理数量不变，每个broker存储空间最少扩容100GB。

当oper_type类型是horizontal时，每个broker的存储空间不变。

new_broker_num

否

Integer

当oper_type参数为horizontal时，该参数有效。

取值范围：最多支持30个broker。

new_product_id

否

String

垂直扩容时的新产品ID。

当oper_type类型是vertical时，该参数才有效且必填。

产品ID可以从查询产品规格列表获取。

publicip_id

否

String

实例绑定的弹性IP地址的ID。

以英文逗号隔开多个弹性IP地址的ID。

当oper_type类型是horizontal时，该参数必填。

tenant_ips

否

Array of strings

指定的内网IP地址，仅支持指定IPv4。

指定的IP数量只能小于等于新增节点数量。

当指定IP小于节点数量时，未指定的节点随机分配内网IP地址。

second_tenant_subnet_id

否

String

实例扩容时新节点使用备用子网的id

当实例扩容使用备用子网，则传入此值

需要联系客服添加白名单才能传入此值

响应参数

状态码： 200

表3 响应Body参数

参数

参数类型

描述

job_id

String

规格变更任务ID。

请求示例

  • 扩容存储空间（按需实例）。

    POST https://{endpoint}/v2/{engine}/{project_id}/instances/{instance_id}/extend

{
  "oper_type" : "storage",
  "new_storage_space" : 600
}

  • 扩容代理数量（按需实例）。

    POST https://{endpoint}/v2/{engine}/{project_id}/instances/{instance_id}/extend

{
  "oper_type" : "horizontal",
  "new_storage_space" : 1600,
  "new_broker_num" : 4,
  "tenant_ips" : [ "127.0.0.1", "127.0.0.2", "127.0.0.3" ]
}

  • 扩容代理规格（按需实例）。

    POST https://{endpoint}/v2/{engine}/{project_id}/instances/{instance_id}/extend

{
  "oper_type" : "vertical",
  "new_product_id" : "c6.4u8g.cluster"
}

响应示例

状态码： 200

实例扩容成功。

{
  "job_id" : "93b94287-728d-4bb1-a158-cb66cb0854e7"
}
